To all whom it 7a2/ty concern.-

Be it known that I, FREDERICK WILLIAM SCHEOEDER, engineer, a naturalized subject of the Queen of Great Britain, residing at Newtown, near Sydney, in the British Colony ot New South lwales, have invented new and useful Improvements in Smoking-Pipes, (for which I have obtained Letters Patent in Great Britain No. 5,6%, dated March 18, 1895,) of which the following is a specification.

This invention relates to certain improvements in smoking-pipes, whereby they may be almost instantly thoroughly cleansed of all iiuid or other matter, and therefore insure a comfortable and healthy smoke, and at the same time be manufactured cheaply.

The essential. feature of my invention consists in a plug, with scraper-heads, adapted to iit an enlarged chamber in the smoke-passage and having certain peculiarly-arranged passages, grooves, and ports so constructed as to allow the ready passage of the smoke, but prevent liquid or other matterfrom reaching the mouthpiece orifice, as hereinafter more particularly described with reference to the accompanying drawings, wherein- Figures 'l and 2 are sectional elevation and sectional plan views, respectively, of a smoking-pipe constructed according to my invention. Figs. 3, a, 5, and 6 are cross-sectional views on lines a, l, c, and d, respectively, of Figs. 1 and 2; and Figs. 7 and S are similar views to Figs. l and 2, but of a slight modification, wherein the plug instead of being formed integral with the mouthpiece is fitted tightly into the bowl end, which practically makes no difference.

The bowl A of the pipe is made, as ordinarily, of wood, clay, meerschaum, or other suitable material, with orifice or channel A' and with bowl A2, having suitable connection to a chamber B of suitable material, preferably impervious to moisture, and preferably such as vulcanite, ebonite, and the like. This chamber B, as in Figs. i and 2, maybe an independent casing or tube iitting tightly on the bowl end A2 and having the mouthpieceplug C ntting within it, or it may, as in Figs. 7 and S, be made integral with the mouthpiece D and fit over the scraper-heads of plug C, which plug is in such case fitted tightly in the bowl end A2.

In the pipe shown in Figs. l to (5 the scraperhead O' has around it a helical channel Ci, having connection by channels O2 or by a space with the bowl-oriice A and by holes or channels C'l with the central passage C5 of the plug or stem. The scraper-head has a groove or hollow channel C7, connected by an inclined channel or passage O3 with the central passage O5 of the plug and connected by port or niche or opening Cg with the chamber B. The bowl-orifice A, in addition to the connection with the central passage by means of helical channel C3 and holes Ci, may have and preferably has connection CX through the scraper-head O' to said passage C5. In use the smoke from bowl A is drawn through plug C= into chamber B by way of opening C and helical channel C5 and holes O4, the central channel or passage C, channel or passage CS, and port or niche C9. In this chamber B any moisture or condensation is deposited, and the smolre passes to the mouth by way of inclined passages D and central draw-off passage D2, and no excess Inoisture or saliva can commingle with nicotine-oil in suck-passages D and D2, as the nicotine-oil cannot pass out of chamber B until. the plug C is removed, when the scraper-heads clear the chamber, and if both parts of the pipe be slightly shaken any remaining moisture, saliva, or nicotine will be entirely removed.

In the slight modification shown in Figs. 7 and 8, the plug C, instead of being formed integral with the mouthpiece, is fitted tightly in the bowl end A2, and the casing of chamber B, being part of the mouthpiece D, iits over the scraper-heads O' and C thereon. The scraper-head C, as in Figs. 1 and 2, has a groove or hollow channel C connected by an inclined channel or passage C'S with the central passage C5 of the plug, and connected by port or niche or opening O with the chamber B, from which the smoke is drawn through inclined passageD to the central draw-oit passage D2 and mouthpiece-orifice, as hereinbefore described.

The pipe is cleared of any extraneous Inatter by simply removing the mouthpiece D,

(and consequently the casing of the chamber 13,) and if both parts be slightly shaken any remaining moisture is entirely removed and the pipe rendered sweet and pure.

Vith pipes manufactured according to my invention there is but little opportunity of the material of the pipe or bowl becoming impregnated With nicotine-oil, as the stem and mouthpiece are, as before stated, preferably constructed of impervious material.

Having described my invention, what I claim isl. In a smoking-pi pe, the combination with a bowl and mouthpiece provided respectively with central smoke-passages A and D2 and an enlarged chamber intermediate said smokepassages, of a plug arranged Within said chamber and provided at its opposite ends with scraper-heads C', C6, the space between said heads communicating with the smokepassage A' by a central passage C5, inclined channel C8, peripheral groove C7 and port C,

and said chamber communicating with the smoke-passage D2 by an linclined passage D substantially as described.

2. In a smoking-pipe, the combination with a bowl and mouthpiece provided respectively with central smoke-passages A and D2 and an enlarged chamber intermediate said smokepassages, of a plug arranged Within said chamber and provided at its opposite ends .with scraper-heads C', C, the'ispace between
